“This dataset should be considered a work in progress”
States:
- NY
- CT
- ME
- NH
- MA
- Federal waters
Species: - “Shellfish” “Multi-trophic or other” “Seaweed” “Finfish”
This data set is not “comprehensive” but provides good sources to look through for individual states (see below). These are polygons.
Florida:
“ESI Human Use and Socio-Economc Resources Points” data
- https://geodata.myfwc.com/datasets/myfwc::esi-human-use-and-socio-economic-resources-points-florida/about
- 2015 data
- 64 sites
- Point data, no area
- Not comprehensive (?), only represents points which are at risk from oil spills (which could be relevant to our project).
Offshore aquaculture in Florida
Other than the above, I can’t find much info for Florida. Google maps shows a couple shrimp farms.
Connecticut:
Shellfish bed managed
However, worst case, we could use the data from the Northeast ocean council dataset:
“Connecticut – Data on Connecticut aquaculture was derived from two datasets provided by the State of Connecticut Department of Agriculture/Bureau of Aquaculture and the State of Connecticut Department of Environmental Protection. One dataset contains the location of natural shellfish beds. Natural beds managed by the state, town or used for recreational harvesting were selected from this dataset, resulting in 1855 polygons. The number of beds in use at any given time is subject to change. The second dataset contains 46 polygons representing the approximate geographical location of permitted “Certificate for Aquaculture Operation” gear sites in the Connecticut coastal waters of Long Island Sound via the State of Connecticut Application for Joint Programmatic General Permit for Aquaculture Department of the Army General Permit. These datasets are up to date as of January 15, 2016. For more information on CT Aquaculture and Shellfish, see the CT Aquaculture Mapping Atlas."

Another map, this is probably what we need (seaweed and shellfish): https://www.arcgis.com/apps/webappviewer/index.html?id=f8799cefbb4c4751a209710d14b9ad46
Washington:
Approved growing areas map
“DNR leases deep water sites for finfish net pens and floating shellfish rafts and longlines. Salmon aquaculture operations have existed in Washington since the 1970s and are scattered throughout Puget Sound. Current net pen leases include salmon aquaculture, delayed-release salmon, and herring. The use of floating shellfish culture began in 1975 with mussel raft culture in Penn Cove. Current floating shellfish culture on rafts or longlines include oysters, mussels, and scallops.”
